The 4 forces that have a fundimental influence on the wind velocity are what?

Pressure Gradiant,

Coriolis Force,

Centripetal force,

Friction forces.

Coriolis force acts at right angles to the (Isobars/wind direction?) and the 4 factors which determine it's strength are what?

Wind direction,

Earth spin, Air density, Wind Speed, Latitude.

In the Southern hemisphere, air flowing out from a (low/high?) pressure system will deflect to it's (right/left?) which produces a (clockwise/anticlockwise?) around a (high/low?)

High

Left

Anticlockwise,

High

When coriolis force is greater than the pressure gradient, the air will flow (clockwise/anticlockwise?) around a (high/low?) and vice versa

Anitclockwise - high

Clockwise - low

When the wind flows paralell to straight isobars, the winds is called a (?) wind, and when it flows paralell to curved isobars it is called a (?) wind.

Geostrophic,

Gradient.

When the friction layer is dense, the strength of the (pressure gradient/coriolis force?) reduces so that the wind starts to flow (across/parallel to?) the isobars, (inward to/parallel to/outward from?) the high.

Coriolis force,

Across,

Outward from.

The wind is said to Veer when it's direction changes in a (clockwise/anticlockwise?) direction.

Clockwise

After Sunrise in the southern hemisphere, the wind will (Veer/Back) and (increase/decresase?) in strength?

Back,

Increase.

When decending into a dense friction layer in the southern hemisphere, the wind will (Veer/Back), and (increase/decrease?) in strength.
